Fig.2 is a side elevation poses. On theshaft N, upon the opposite side of the standard, is fixed the disk O, and between this disk and a collar P, also fast on said shaft, is loosely sleeved the collar Q, from one side of which projects the arm q, which is limited in its movement by means of the stops q q2 on the face of said disk, as will be hereinafter more fully described. From the opposite side of said collar Q projects the arm g3, and to the said arm g3 is pivoted one end of the curved lever R, the opposite end of which is in turn pivoted to one end of the lever S, the opposite end of which is pivoted to the disk on the pivot r', and is formed near its pivot with an enlargement or detent r2, which is preferably, though not necessarily, provided with an anti-friction roller r3. Normally this detent or the roller thereof projects through or beyond the periphery of the disk', and is aided in assuming this position by means of the spring r4, fixed at one end, as at rf", to the face of the disk, and bearing with its free end upon said lever S near its pivot, as shown best in Fig. 3. Loosely sleeved on the shaft N, beyond the collar P, is the wheel T, provided with the teeth t on its periphery, and also formed with an aperture t', through which works the pawl U. This pawl is pivoted to the wheel, as shown at t2, and is normally held projected through said aperture by means of the spring t4,secured to saidl wheel and bearing on the pawl, as shown in Fig. 4. These parts just described are inclosed in a case V, secured to the back of the standard H, and provided with a removable cap or cover V', which is held in position by means of the screws u.

WV is a plate iixed within the casing and forming a bearing for the shaft N, and provided with an opening w, through which the pawl U projects at predetermined periods, as will be more fully hereinafter s et forth.

The case V is provided with a slot o', through which the detent r2 or its roller 'r3 normally projects, and longitudinally through the top of the casing is a slot or aperture o2, in which travels the rack-bar X, projecting downwardly from the carriage and supported therefrom in any suitable manner-for instance, by means of the bars o3. i

The operation of this part of our improvement is as follows: The spring K is first wound up' by means of a suitable key or crank, the shaft J being extended to the front of the machine and provided with a squared end for this purpose, as shown best in Fig. 2. The letter-keys are operated upon in the usual manner, as the carriage travels from right to left, being actuated in the usual maliner by a spring. (Not shown.) The rack-bar X moves with said carriage and works in the teeth of the wheel T. The rotation of said wheel by means of'this engagement causes the pawl U to be withdrawn from the opening w in the plate W, and depresses it so that in the further rotation of said wheel said pawl willengage with the arm q of the collar Q; and as the wheel is still further revolved in the direcshown. riage before the end of a line is reached, it is tion of the arrow in Fig. 3 the said arm is carried around with the wheel by reason of the engagement of the pawl therewith until the detent r2 is drawn in so as to release the same from its bearing on the casing, and as soon as said detent is released fromits bearing the spring K, being connected to the shaft on which the disk is fixed, causes said disk to revolve until it is again stopped by the engagement of said detent with its bearing onthe casing. At the point on the casing where the detent bears we preferably provide an anti-friction roller to2, to decrease the friction. When the detent is released from its bearing the wheel T is rotated in the reverse direction until the pawl U springs into the aperture in the plate W. This rotation of the wheel, through the engagement of its teeth with the rack-bar X on the carriage, causes the carriage to move from left to right and return to the commencement of a line. As another line is commenced the same operaltion is repeated. When the spring K runs down, it is only necessary to wind it u p again; and in order to notify the operator when the spring is about run down we provide an alarm consisting of a bell X secured to the casing,

vand the hammer thereof provided with a lever X2, arranged in such a position that as the spring becomes distended in unwinding to a certain extent it strikes said lever and causes the hammer to strike the bell and sound an alarm.

The spring K should be stronger and more powerful than the spring which actuates the carriage from right to left, in order that it lmay be sure to cause the carriage to return to the right when the parts have assumed the position at the end of the line, as above described.

It often happens that in the use of the typewriter one completes a sentence before the end of the line is reached and wishes to begin a new line without going to the end of that one. In order to return the carriage under such circumstances, we provide the following mechanism: To the right-hand side of the machine we provide an extra key-lever Y, pivoted at y to the rear of the machine, and carrying an upright arm or rod y', connected with one end of the lever y2, pivoted at 'g3 on the standard H, and at its other end arranged to engage with the detent'h'2 or its roller r3, as

When it is desired to return the car- Ioo` IIC

known and will be readily understood. an arm attached to the right-hand side of the frame of the machine and arranged at an angle to the travel of the carriage, as shown, and in such a position as to engage the spacing-lever as the carriage approaches the righthand side of the machine to the commencement of a line, and as said lever rides up said inclined arm it causes the same to be raised at its forward end. and therefore depress its rear end, and, by reason of the engagement of the ratchet and pawl, to feed the paper Y forward.

In order to regulate the space or number of notches the paper is to be fed, we connect thearm 2 to the frame as follows: 3 is a pin or pintle on the frame, and the end of the arm 2 is formed with an eye 4, sleeved on said pin, whereby it may be turned to different angles, being held in its adjusted positions by means of the set-screw 5. This arm 2 also serves to bring the carriage gradually to a standstill, lessening the shock which might otherwise be occasioned if the carriage, by the force of the spring K, were brought suddenly against its stop at the right-hand side of the machine.

The carriage-returning mechanism above described, although particularly serviceable for the purpose for which it is shown in this specification, is well adapted to other uses, and We therefore wish to be understood as not restricting ourselves to its use in connection with a type-writing machine, as it is evident that it may be applied to other analogous uses in which like results are accomplished.

Various modifications in detail may be resorted to without departing from the essence of or detracting from the merits of the invention.
